FABRIC-HOLDING FRAME FOR EMBROIDERING-MACHINES.

Specification of LettersPatent. Patented Sept. 10, 1918..

Application filed. April 28, 1918. Seria1No. 230,207.

To all whom it may concern:

Be it known that we, ABRAHAM FEIL, a citizen of the United States of America, and SAMUEL L. SCHWARTZ, a subject of the King of Rumania, both residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Fabric Holding Frames for Embroidering-Machines, of which the following is a specification.

This invention has reference to attachments on embroidering machines of the Groebli or Zahn type with a vertical frame in front of which sets of needles and other implements move horizontally across the fabric usually stretched over the plane of the frame.

When short pieces of fabric such as parts of ladies waists or the like are to be embroidered, then in order to perform the embroidery work on all pieces simultaneously and with great accuracy as to the design required and the particular location of the embroidery, it becomes necessary to use a sepa rate or auxiliary frame which is suspended from or supported in the frame of the embroidery machine. A

Our invention deals particularly with the construction of such auxiliary frame for the support of several small pieces of fabric on which embroidery is to be produced.

One object of our invention is to so construct the said frame that the pieces of fabric can be easily attached to and removed from said frame and can be properly adj usted to a position which will allow of the designs being produced onthe several pieces of goods at the places desired.

Another object of our invention is to provide means which will serve as a guide to the operator to enable him to arrange the needles or other implements in the proper position with respect to the pieces of fabric.

A further object. of our invention is to provide means for gathering and concealing the ends or edges of thepieces of fabric which, in case the latt'erare cut on a bias, as usually are the parts of a ladys waist, would, when stretched in the auxiliary frame, be liable to project over the face of the fabric and interfere with the embroideryv work performed thereon. j I

And a further object of our invention is to provide locking means for holding the above named means in position.

With theseand'other objects in view, our

' another.

inventionconsists in the combination, arrangement and construction of parts aswill be hereinafter more fully described and set forth in the appended claims.

In the accompanying drawings which form part of this specification and in which similar reference characters denote corresponding parts, Figure 1 is a rear elevation of the auxiliary frame; Fig. 2 is a partial front elevation of the auxiliary frame with some parts removed; Fig. 3 is an enlarged rear view of a part of the frame with a piece of fabric shown as attached thereto; Fig. 4 is an end view of the part shown in Fig. 3; Fig. 5 is a section on line 5-5 of Fig. 3 Fig. 6 is a section on line 66 of Fig. 3; Fig. 7 is a rear view of a guide to be used in connection with said frame; Fig. 8 is a longitudinal view of one of the removable bars serving for the attachment of the fabric to the frame; Fig. 9 is a similar View of a second bar used in connection with said frame; Fig. 10 is a section on line 101O of Fig. 7; Fig. 11 is an elevation on line 11-11 of Fig. 8 and Fig. 12 is a section on line 1212 of Fig. 9.

Referring specifically to the drawing, the auxiliary frame which is to be suspended from or supported on the frame of an embroidering machine of the type of Groebli or Zahn or any other type of embroidering machines is a skeleton frame consisting of bars 1, 2 which are joined together by rods 3, 4: or in any other way, so as to form a frame of substantially rectangular shape.

With the Groebli or Zahn type of embroidering machine, this auxiliary frame is supported in the machine so that the bars 1, 2. extend horizontally and longitudinally while the rods 8, 4 form the end pieces thereof and extend vertically. Each of the bars 1, 2 is provided with a number of bores 5, the bores in the two bars being adapted to register with one another. These bores 5 extend transversely throughout the thick ness or width of the bars and serve as bearings for rods 6 adapted to extend transversely through the space formed between the bars 1, 2 and parallel to the end rods 3, 4. Each rod 6 is composed of two longitudinal separable parts or sections 6, 6 of semicicular cross section having flat and even base surfaces 6 which, when the parts areassembled, are adapted to bear on one In length the two parts 6, 6 are p so admeasured that when assembled in the jbores 5 o'f'the barsl, 2 excepting that the tended portion 6 of the bar 6 doubled in thickness and made perfectly circular in cross section so as to fitin the cylindrical bore deem bar 1. The outwardlyiproiee he' 9 1 6 of he 5 o sq e c as sect onv and serves to receive a small ratchet \i l ieel 7 which has 'a correspondingly shaped her 7 gz s'sa end he Pa t6 atthepoint where itis enlarged inthickness forms a shoulder 6 against which rests vthe corresponding end of the part -6 when assembled in the frame. The piece of fabric F, which is to be embroidered, is attached .to thelz i uxiliary"frame as follows:

The shorter part 6 of the rod 6 having been removed one edge or end ofthe fabric F is put around the fiat surface 6 of the part 5, then the part 6 is put in position so as in cooperation with the part 6 to clamp the fabric. Similarly the opposite edge of a the fabric is clamped between the 6 of a next following rod 6.

Adjacent to the ratchet wheel 7 of each part 6, is arranged a pawl 8 adapted to cooperate with it. a This pawl is mounted on a screwbolt 9 which works in athreaded bore 5 provided at one side of each bore 5. When the parts have been assembled and the longitudinal edges of the fabric clamped between the parts 6, 6 of two opposite rods 6 the part 6 of one of the rods or of both rods are turned around their axes by means of a key (not shown) to be applied to the Square end thereof, and thereby the edges or ends of the fabric become wound around the parts 6 6 of the rods 6 and is stretched to the desired extent.

As will be seen from the drawing, the bores 5 of a bar are not equally spacedapart but are arranged in pairs or so that at one parts 6 .side of a bore there is one close to it and at the opposite side there is a bore farther rembved. This enables-the arrangement of the rods 6 so that separate pieces of fabric follow closely one another, instead of at greater intervals which would entail loss of space.

,Of course instead of this arrangement, the bars 1, 2 may each have a-series of bores very close to one another, which will allow any desired spacing between the rods fi-used for pn e piece of fabric andthe rods for sep ar te p eces .When larger orsmallerpieces of goods are t h hmhhhider then th reds 6 a e djustedaccordingly by removing their parts from the particular bores 5 they are in and placing them into bores lying farther or nearer apart. The pawls 8 are accordingly readjusted. c

As the spacing between two successive rods 6 for separate pieces of fabric may be smaller than the diameter of the ratchet wheels, 7,""as ii 1' the example shown, the.

These extended ends are adapted to engage int-0 bores of the bars 1 and 2, which bores may be separate from those marked 5 or may be the same. By reason of the nonsymmetrical construction of the frame 15, the latter, when mounted in the auxiliary frame over the back of the fabric, will extend with its upper edge (in the drawing with its edge adacent to the longer ends of the bars 16, 17) below the bar 1 a certain distance and indicate the uppermost end of the embroidery design to be embroidered on the fabric. This edge will be visible in front through the more or less transparent material or fabric and the operator guided by it will accordingly adjust the implements of the machine to start the embroidery on a line coinciding with the said edge. The distance between the longitudinal edges of the frame 15 determines the width of the embroidery. If the design is of lesser or larger width a narrower or broader frame is to be used.

It must also be stated that the teeth of the ratchet wheels are of small pitch to enable a fine stretching of the pieces of fabric.

While we have described the details of the construction, we do not wish to restrict ourselves to the same since various modifications may be made by those skilled in the art without departing from the principle of our invention.

What we claim and desire to secure by Letters Patent is:

1. Means for the attachment of separate pieces of fabric on embroidery machines, consisting of a skeleton frame, removable rods, each composed of longitudinal separable sections and rotatively and removably borne in said frame, said separable sections of each rod resting loosely on one another but held together by their engagement in said frame and being adapted to receive between themselves an edge or end of a piece of fabric and means to permit the fine stretching of the fabric.

2. Means for the attachment of separate pieces of fabric on embroidery machines, consisting of a skeleton frame, having a se Copies of this patent may be obtained for five cents each, by addressing the ries of bores in opposite sides, the bores in one side coinciding with those in the opposite side, rods each composed of longitudinal separable sections and rotatively and removably borne in said bores, said separable sections of each rod resting loosely on one another but held together by their engagement in said frame and being adapted to clamp an edge or end of a piece of fabric, and means for permitting fine stretching of said fabric.

3. Means for the attachment of separate pieces of fabric on embroidery machines, consisting of a skeleton frame having a series of bores in opposite sides thereof, rods borne in said bores and each consisting of two longitudinal separable sections loosely resting on top of one another but held together by their engagement in the said bores and adapted to engage an edge or end of the fabric, one section being extended outwardly of the frame, a ratchet wheel mounted on said extended end and pawls removably fastened to said frame to cooperate with said ratchet wheel.

1. The combination with a fabric frame, of removable rods therein for the attachment of separate pieces of fabric, and a guard of pliable material to fit over two adjoining rods to hold the tail ends of the fabric from projecting over the surface of the fabric and tiltable means on said frame to engage said guard and hold the same in position.

5. The combination with a fabric frame, of removable rods thereon for the attachment of separate pieces of fabric, a guard of pliable material to fit over two adjoinin rods holding separate pieces of fabric and serving to prevent the tail ends of the fabric from projecting over the face of the fabric, and means for locking said guard in position and consisting of U-shaped members tiltably supported on said frame and means for locking said tiltable members in position.
